This commentary discusses the balance of phosphodiesterase and guanylate cyclase activities in vertebrate photoreceptors at moderate light intensities. The rate of cGMP hydrolysis and synthesis seem to equal each other. Ca2+as regulator of both enzyme activities is also effectively buffered in photoreceptor cells by cytoplasmic buffer components.

_Abstract_: The recent proliferation of the term “_Psychological Humanities_” (PH) raises many questions, not least of which is the wide variety of ways in which the term is employed. After noting some of this variety, we focus on a related question that has been insufficiently discussed: the extent to which PH represents a genuinely new contribution and approach, and to what extent it represents a renaming. To address this question, we examine examples of past efforts to theorize the relation between (...) psychology and the humanities. We explore Dilthey’s argument in favor of “two sciences” and C.S. Snow’s description of “two cultures”, which offer somewhat different models of the relations between science and the humanities. We then discuss the application of these models to the discipline of psychology, first by Dilthey himself and later by Sigmund Koch, noting similarities to descriptions of the project for PH as currently described. We question the need for a renaming of the project and call attention to the risk of PH exhibiting its own form of presentism while critiquing the presentism of (in) “mainstream” psychological science. _Keywords_: Psychological Humanities; Wilhelm Dilthey; C.P. Snow; Sigmund Koch; Philosophical and Theoretical Psychology _Cosa c’è in un nome? Le Psychological Humanities e la logica del presentismo_ _Riassunto_: L’uso crescente del lemma _Psychological Humanities_ solleva diversi problemi, non ultimo l’ampia varietà di modi in cui questo è impiegato. Dopo aver portato l’attenzione su alcuni usi di questo lemma, ci concentreremo su una questione collegata, fin qui trattata in maniera insoddisfacente: fino a che punto le _Psychological Humanities_ rappresentano un contributo e un approccio davvero innovativo e in che misura sono solo una nuova denominazione. Per affrontare questo problema, prenderemo in esame alcuni tentativi compiuti in passato per trattare il rapporto tra psicologia e discipline umanistiche. Prenderemo in considerazione l’argomento di Dilthey in favore delle “due scienze” e la posizione di C.S. Snow circa l’esistenza delle “due culture”, che offrono modelli leggermente diversi rispetto alla relazione tra scienza e discipline umanistiche. Discuteremo poi l’applicazione di questi modelli alla psicologia, seguendo dapprima lo stesso Dilthey per poi considerare il modello di Sigmund Koch, mettendo in risalto le loro affinità con le descrizioni correnti del progetto delle _Psychological Humanities_. Discuteremo poi la necessità di una nuova denominazione per questo progetto per richiamare l’attenzione sul rischio che le _Psychological Humanities_ possano esibire una propria forma di presentismo mentre criticano il presentismo della scienza psicologica “mainstream”. _Parole chiave_: Psychological Humanities; Wilhelm Dilthey; C.P. Snow; Sigmund Koch; Psicologia filosofica e teoretica. (shrink)

The recent financial crisis has triggered an intense debate about the role of banks in society, presumably changing the criteria used in the evaluation of organizations. Against this backdrop, we investigate the changing role of banks’ organizational features in shaping different dimensions of banks’ organizational reputation. Using the media as an important evaluator, we measure the reputational dimension of visibility based on the frequency of newspaper articles and the reputational dimension of favorability based on the sentiment of newspaper articles. Drawing (...) on social judgment research for developing our hypotheses, we expect that organizational features such as financial performance and familiarity become more important determinants of organizational reputation in times of crisis. Our results support this expectation, suggesting stronger effects of these organizational features on the visibility and favorability of banks during a crisis. These findings provide novel empirical evidence on how the importance of drivers of organizational reputation changes in times of crisis and highlight areas for managerial attention. (shrink)

A modal analysis of luck, due to Duncan Pritchard, has become quite popular in recent years. There are many reasons to like Pritchard’s analysis, but at least two compelling problems have been identified. So I propose an alternative analysis of luck based on the laws of statistical mechanics. The statistical analysis avoids the two problems facing Pritchard’s analysis, and it has many other attractive features.
